El convertidor de frecuencia 18 incluye también medios de medición de tención de CC 8, que están dispuestos para medir la tensión del circuito intermedio de tensión continua 13, y un controlador 10, que está dispuesto para controlar la operación del primer elemento convertidor 11. En términos de transmisión de datos, los medios de medición de tensión de CC 8 están conectados al controlador 10 para transmitir datos asociados con la tensión del circuito intermedio de tensión continua 13 al controlador 10. El controlador 10 es capaz de ajustar un componente Id asociado con la magnetización y un componente Iq asociado con el par de la corriente que pasa a través del acoplamiento de CA del primer elemento convertidor 11.The frequency converter 18 also includes DC voltage measurement means 8, which is arranged to measure the voltage of the DC intermediate circuit 13, and a controller 10, which is arranged to control the operation of the first converter element 11. In In terms of data transmission, the DC voltage measuring means 8 is connected to the controller 10 to transmit data associated with the voltage of the DC intermediate circuit 13 to the controller 10. The controller 10 is capable of adjusting an associated I d component with magnetization and an I q component associated with the torque of the current passing through the AC coupling of the first converter element 11.
El controlador 10 está dispuesto para controlar la potencia del generador de CA 2 sobre la base de los datos asociados con la tensión del circuito intermedio de tensión continua 13 y recibida desde los medios de medición de tensión de CC 8. El control de potencia se implementa de tal manera que el controlador 10 cambia el componente Iq asociado con el par de la corriente que pasa a través del acoplamiento de CA del primer elemento convertidor 11 para obtener la potencia deseada del generador de CA 2.The controller 10 is arranged to control the power of the AC generator 2 based on the data associated with the voltage of the DC voltage intermediate circuit 13 and received from the DC voltage measuring means 8. The power control is implemented such that the controller 10 changes the I q component associated with the torque of the current passing through the AC coupling of the first converter element 11 to obtain the desired power from the AC generator 2.
El regulador de tensión 4 de los medios de generación están dispuestos para regular la magnetización del generador de CA 2 sobre la base de los datos asociados con la tensión del acoplamiento de CA y recibidas desde los medios de medición de tensión de CA 6.The voltage regulator 4 of the generating means is arranged to regulate the magnetization of the AC generator 2 based on the data associated with the AC coupling voltage and received from the AC voltage measuring means 6.
El primer elemento convertidor 11 está dispuesto para proporcionar una cantidad limitada de componente de corriente relacionado con la magnetización Id en la corriente que pasa a través del acoplamiento de CA, limitando la cantidad limitada de tal manera que el regulador de tensión 4 puede permanecer dentro de su rango de operación normal en todas las situaciones de uso. La cantidad de componente relacionado con la magnetización Id proporcionado por el primer elemento convertidor 11 se controla con el controlador 10.The first converter element 11 is arranged to provide a limited amount of current component related to the magnetization I d in the current passing through the AC coupling, limiting the limited amount such that the voltage regulator 4 can remain within out of its normal operating range in all usage situations. The amount of component related to magnetization I d provided by the first converter element 11 is controlled by the controller 10.

La cantidad de magnetización del generador de CA 2 afecta a la tensión de salida del generador de CA 2 y, en consecuencia, a la tensión en el acoplamiento de CA del conjunto de generador. De acuerdo con lo anterior, es posible regular la tensión del acoplamiento de CA del conjunto de generador usando el regulador de tensión 4 solo o usando tanto el primer elemento convertidor 11 como el regulador de tensión.The amount of magnetization of the AC generator 2 affects the output voltage of the AC generator 2 and, consequently, the voltage at the AC coupling of the generator set. According to the above, it is possible to regulate the voltage of the AC coupling of the generator set using the voltage regulator 4 alone or using both the first converter element 11 and the voltage regulator.
El regulador de tensión 4 y el controlador 10 del primer elemento convertidor 11 operan independientemente y sin intercambio recíproco de datos. Por lo tanto, el regulador de tensión 4 tiende a regular la tensión del acoplamiento de CA del conjunto de generador de acuerdo con su valor objetivo independientemente de la operación del primer elemento convertidor 11.The voltage regulator 4 and the controller 10 of the first converter element 11 operate independently and without reciprocal data exchange. Therefore, the voltage regulator 4 tends to regulate the voltage of the AC coupling of the generator set according to its target value regardless of the operation of the first converter element 11.

A partir de la figura 2 se desprende que el primer elemento convertidor 11 comprende seis transistores bipolares de puerta aislada S1 a S6 y seis diodos D1 a D6, estando cada uno de los diodos D1 a D6 acoplado en antiparalelo con el correspondiente transistor bipolar. Los transistores bipolares de puerta aislada, es decir, transistores IGB, y las conexiones de puente formadas de este modo se conocen comúnmente en el campo y, por lo tanto, no se describen con mayor detalle en el presente documento.Figure 2 shows a simplified circuit diagram of the first converter element 11. From figure 2 it appears that the first converter element 11 comprises six insulated gate bipolar transistors S1 to S6 and six diodes D1 to D6, each one being diodes D1 to D6 coupled in antiparallel with the corresponding bipolar transistor. Insulated gate bipolar transistors, i.e., IGB transistors, and bridging connections formed in this way are commonly known in the field and therefore are not described in further detail herein.
La estructura del segundo elemento convertidor 12 puede ser la misma que la del primer elemento convertidor 11 que se muestra en la figura 2. En ese caso, el conjunto del generador es un accionamiento eléctrico de cuatro cuadrantes, en el que la electricidad puede ser suministrada desde el generador de CA 2 al motor eléctrico 16 y viceversa. En el accionamiento eléctrico de cuatro cuadrantes, la velocidad de rotación y la dirección del par de la máquina eléctrica pueden variar libremente. El accionamiento de cuatro cuadrantes se puede utilizar en aplicaciones de grúas, por ejemplo.The structure of the second converter element 12 can be the same as that of the first converter element 11 shown in Figure 2. In that case, the generator assembly is a four-quadrant electric drive, in which electricity can be supplied from AC generator 2 to electric motor 16 and vice versa. In the four-quadrant electric drive, the rotation speed and torque direction of the electric machine can be freely varied. The four quadrant drive can be used in crane applications, for example.
En realizaciones alternativas de la estructura del segundo elemento convertidor puede diferir de la del primer elemento convertidor. En lugar de la unidad de cuatro cuadrantes, el conjunto generador también puede estar dispuesto para ser una unidad de un cuadrante o de dos cuadrantes. Además, el conjunto generador puede comprender medios de resistencia de freno.In alternative embodiments the structure of the second converter element may differ from that of the first converter element. Instead of the four-quadrant unit, the generator set can also be arranged to be a one-quadrant or two-quadrant unit. Furthermore, the generator set may comprise brake resistor means.

Además de varios motores de CA, los motores eléctricos alimentados por el conjunto de generador también pueden comprender motores de CC. Cada motor de CA puede ser alimentado por el inversor correspondiente. Cada motor de CC se puede suministrar directamente desde el circuito intermedio de tensión continua o mediante el convertidor de CC correspondiente. Además, el circuito intermedio de tensión continua del conjunto generador puede estar dispuesto para alimentar cargas de algún otro tipo aparte de los motores eléctricos. The DC link of the generator set can power more than one electric motor. In addition to various AC motors, the electric motors powered by the generator set may also comprise DC motors. Each AC motor can be powered by the corresponding inverter. Each DC motor can be supplied directly from the DC link or via the corresponding DC converter. Furthermore, the intermediate DC voltage circuit of the generator set may be arranged to supply loads of some other type apart from electric motors.
En una realización de la invención, el generador de corriente alterna es un generador síncrono sin escobillas, y la energía de magnetización que requiere es producida por un generador auxiliar de imán permanente proporcionado sobre su eje. También se pueden usar generadores de CA de otros tipos. Además, es posible conectar al circuito intermedio de tensión continua del conjunto de generador una pluralidad de generadores de CA, cada uno de los cuales puede conectarse al circuito intermedio de tensión continua por medio de un rectificador específico.In one embodiment of the invention, the alternating current generator is a brushless synchronous generator, and the magnetizing energy it requires is produced by a permanent magnet auxiliary generator provided on its axis.
